The effects of tillage and residue input amounts on soil phosphatase (alkaline phosphomonoesterase ALP, acid ACP, phosphodiesterase PD, inorganic pyrophosphatase IPP) activities phosphorus (P) forms (total P, organic available P) were evaluated using soils collected from a three-year experiment. results showed that no-till increased total but not P as compared to conventional treatments. Total was inputs crop for treatment. There higher ALP IPP in treatments, while PD activity found treatments had no significant effect ACP activity. Overall with an increase amounts. Soil correlated negatively positively other activities. Organic positive correlation activity, negative Available Our data suggests could contents enhance the phosphatase.
